Django filters date range filter is not working

I really don't understand how to connect these two fields or should I just create one. On my front, I have a starting date and end date I can not connect to the backend properly using django-filters Please see the below code
My filters.py
class VideoFolderFilter(FilterSet):
name = CharFilter(field_name='name', lookup_expr='icontains', widget=forms.TextInput(attrs={'class': "form-control"}))
subscription_plan = ModelChoiceFilter( label='subscription_plan', queryset=Plans.objects.all())
start_date_range = DateFromToRangeFilter(field_name='start_date_range', widget=forms.TextInput(attrs={'class': "form-control"}))
end_date_range = DateFromToRangeFilter(field_name='end_date_range', widget=forms.TextInput(attrs={'class': "form-control"}))
def get_date_range(self, start_date_range, end_date_range):
return Sample.objects.filter(sampledate__gte=start_date_range,
sampledate__lte=end_date_range)
class Meta:
model = VideoFolder
fields = '__all__'
widgets = {'start_date_range': DateInput(),}
exclude = [ 'thumbnail_link', 'link', 'name']
My views.py
#login_required
def search_videos(request):
if Subscriber.objects.filter(user=request.user).exists():
subscription = Subscriber.objects.get(user=request.user)
else:
message = "Seams like you don't have subscription with us please select one of the plans"
return redirect(reverse('main'))
video_filter = VideoFolderFilter(request.GET, queryset=VideoFolder.objects.filter(type='video').order_by('-created_date'))
videos = video_filter.qs
return render(request, 'search-videos.html', locals())
Should I change the views.py to query if yes how to date range and other fields will be included
And my search-videos.html
<div class="search-video-form-section mb-3">
<p>Use one or more filters to search below</p>
<form method="GET">
<div class="form-group mb-px-20 filter-form">

<!-- <input type="text" class="form-control" placeholder="Keyword" /> -->
{{ video_filter.form.name }}
</div>
<div class="d-flex flex-wrap date-box">
<div class="form-group input-field">
<label class="text-base">Start Date</label>
<div class="input-group input-daterange">

</div>
</div>
<div class="form-group input-field">

<div class="input-group input-daterange">

</div>
</div>
<div class="form-group filter-form">

This is my forms.py:

This is my models.py
class Project(models.Model):

project_location = models.CharField(max_length=30)
operator = models.CharField(max_length=30)

I am not getting any errors, but the data I save is not saved in the database. Can anyone see what I need to fix?

In your view which directs you to html page :
def project(request):
if request.method == "POST":
form = ProjectForm(request.POST)
if form.is_valid():
form.save()
else:
print("Invalid input from user") # for debugging only, handle according to your need
form = ProjectForm()
all_items = Project.objects.all()
return render(request, 'project.html', {'form': form, 'all_items':all_items})
In your html
<form action="{% url 'url_name_for_your_project_view' %}" method="POST">
{% csrf_token %}
{{ form }}
<input type="submit" value="submit">
</form>

Keep data in the form after submit

I am implementing search by two fields in form in Django.
I want to keep input data after search.
For example I input "C++" and chose "IT"
then I received Default values
I tried to parse request variable --- e.g. data = request.POST.copy()
but did not achieved result. What is the reason of this problem?
How can I solve this problem?
This is my code:
models.py

about = models.TextField()

title = models.CharField(max_length=200)
salary = models.CharField(max_length=200, default='40.000')
text = models.TextField(default="The text about vacancy")
city = models.CharField(max_length=200, default='Москва')
date_str = models.CharField(max_length=50, default='12 сентября')
created_date = models.DateTimeField(default=timezone.now)
published_date = models.DateTimeField(blank=True, null=True)
CHOICES = [

In your search results template, you should use {{ query }} and {{ query2 }} and a little bit of logic to populate the text and drop-down boxes.

I can't submit the form even if it is valid

I have used CreateView for a form, but the form is not being submitted even when it is valid. It just redirects to the same page again.I am using the form_id for from fields, and it even submitted once or twice but now it is just not working.
models.py
class Centre(models.Model):
name= models.CharField(max_length=50, blank=False, unique=True)
address = models.CharField(max_length =250)
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$',
message="Phone number must be entered in the format: '+999999999'. Up to 10 digits allowed.")
contact = models.CharField(max_length=100, blank=False)
phone = models.CharField(validators=[phone_regex], max_length=10, blank=True)
views.py
class centre(CreateView):
fields = ('name','address','contact','phone',)
model = Centre
success_url = reverse_lazy("NewApp:logindex")
def form_valid(self, form):
form.save()
return super(centre, self).form_valid(form)
template :
<form method="POST">
{% csrf_token %}
<div class="col col-md-12">
<div class="fieldWrapper" >

</div>
</form>

You have the wrong name attribute for the contact field, as a result of which it is not being submitted. At the same time, you are not outputting errors for that field.
(Note, you really should use the Django form tags to output the input elements; that would have avoided this situation, as well as pre-populating the fields when the template is redisplayed after validation.)

How can I know which input tag a particular file in request.FILES was uploaded from?

Problem Description:
I have a django view and template which displays several paragraphs of data, which are retrieved from a Model. Below each one, is a <input type="file"> tag, for uploading images related to each row of data. When user uploads files, he may upload 1 to several files for one particular row of the model, or he may choose not to upload files for one or more models. I need to save these files with a foreign key to that particular row. I am not using django forms for this.
To explain once again, there are several file tags in my html, each below a particular set of text from different rows of a model. At POST, all files become collected into a list within request.FILES, with no clue as to from which input tag each was uploaded. I need to differentiate between files uploaded from different file tags, as these need to be saved to the model, referencing different rows by foreign key. How can I know which input tag a particular file in request.FILES was uploaded from?
My model:

All the files get into a Querydict collection. I am unable to differentiate which section it belongs to. Is there any way I can tag specific file tags so that when the form is submitted, I can iterate the list and save each file by tagging them to an individual section heading. The database part is easy. I want to know how to build the file tags/html.

First, don't name fields with []. That's a PHP/Rubyism, there's no need for it in Django.
But the way to have different names is to give the inputs those names. The name attribute of the input is what is used as the key in the FILES/POST dictionaries.
